In general, there is a consensus that persimmons require pollen transfer by an outside agent and that this may be achieved through an insect vector  (McGregor 1976).  Most commercial persimmon cultivars in Australia are pistillate (female) constant (not self-compatible), therefore pollen-producing cultivars may need to be inter-planted with the main cultivar.  Many important polliniser cultivars are monoecious and bear inferior fruit, therefore pollinisers have been selected to provide for specific pistillate cultivars or for their adaptation to local conditions (George et al. 1997).  McGregor (1976) stated that honey bees and bumble bees visit persimmon blossoms freely for nectar and pollen and appear dependable agents in the transfer of pollen. 

Pollination in Queensland has been insect mediated with the European honey bee (Apis mellifera) or other bee species such as native Australian bees (Trigona spp) (George et al. 1997).  George et al. (1993) observed that under Australian conditions honey bees were more attracted to flowers of the polliniser trees due to the greater abundance of flowers and/or pollen and nectar in the flowers.  Reports by Fukae et al. (1987) suggest that at least 20 honey bee visits per flower were required for adequate pollination.
